Summary
Semaglutide slows gastric emptying by up to 50%, thereby increasing stool water loss and helping explain why bowel movements become more complex and less frequent.
About 30% of patients taking semaglutide report constipation, making it a common side effect clinicians routinely monitor.
Constipation on semaglutide can be prolonged, with a median duration of 47 days in a large trial versus 35 days for placebo, so issues often last weeks during dose escalation and early maintenance.
Small, steady habit changes reduce symptoms; for example, aiming for 2 to 3 litres of fluid per day and working toward 25 to 30 grams of fiber daily, rather than sudden, significant increases.
Daily movement and routines matter, with 20 to 30 minutes of light activity or a 10 to 15-minute post-meal walk recommended to nudge gut motility, and using warm drinks and scheduled bathroom times as behavioral cues.
When constipation appears after a dose increase, clinicians advise pausing escalation and extending the current dose for an extra week or two while tracking one habit change at a time to see which tweak actually helps.
MeAgain's GLP-1 app addresses this by centralizing medication timing, hydration, nutrition, activity, and symptom tracking so correlations between habits and constipation can surface in days rather than weeks.
Why Does Semaglutide Make You Constipated?
Semaglutide slows digestive movement and reduces appetite, so stool spends more time in the colon and becomes drier and harder to pass; eating and drinking less at the same time removes the fiber and fluid that usually keep bowel movements regular. Changes in gut hormones from GLP-1 receptor activation also shift motility signals, so altered bowel habits are a predictable part of the treatment for some people.
Understanding the Causes of Constipation with Wegovy
The drug acts like a key into GLP-1 receptors throughout the gut and brain, which lowers hunger and slows the mechanical pace of digestion. That slower pace includes delayed stomach emptying and reduced small intestine transit. When content moves more slowly, it loses water and firms up, which makes stool more difficult to pass.
Gastric Slowdown Causes Constipation
Semaglutide slows gastric emptying by up to 50%, which can contribute to constipation. This slowdown is a key mechanism linking the medication to bowel irregularities. Think of the colon like a conveyor belt: when it moves more slowly, its contents become drier and more compacted.
Why Reduced Appetite Matters, Too
When you feel full on smaller portions, total fiber and fluid intake often drops unless you deliberately replace them, and that decline lowers stool bulk and softness. After coaching patients through dose increases over the first 6 to 12 weeks, the pattern became clear: constipation clustered in the weeks when appetite and meal size fell fastest, and it was often avoidable when hydration and fiber were consistently tracked and nudged. That emotional reality matters because discomfort can be demoralizing, even when the benefits of weight loss are clear.
How Gut Hormones Change Bowel Signals
Beyond mechanical slowing, GLP-1-related hormones shift neural and secretory signals in the gut, which can change stool frequency and consistency. These hormonal effects are less obvious day to day than "ate less, pooped less." Still, they explain why some people see alternating diarrhea and constipation rather than a single predictable effect.
Is It More Common to Experience Diarrhea or Constipation with Wegovy?
Diarrhea shows up more frequently overall, but constipation is still a common side effect and not rare. Clinical reports place constipation among the top side effects for adults on Wegovy, and approximately 30% of patients taking semaglutide report experiencing constipation, which captures that prevalence in plain terms, which helps explain why clinicians flag it routinely during follow-up. The emotional pattern I see with patients is consistent: they worry about digestive changes, but most keep the medication because the metabolic and weight benefits matter more to them than transient discomfort.
How Long Does Constipation Last on Semaglutide?
Duration varies with behavior, dose changes, and individual physiology, but it can linger. A large 2022 trial that monitored digestive side effects found a median duration of constipation of 47 days in people on semaglutide, compared with 35 days on placebo, suggesting the effect often persists for weeks during dose escalation and early maintenance. In practice, people who immediately boost water intake and prioritize soluble and insoluble fiber tend to shorten that window; those who try to "wait it out" without tracking tend to feel stuck longer.
Informal Tactics Fragment Care
Most patients manage it without stopping treatment, but there is a hidden cost to informal self-management. Most people handle this by drinking more water and adding fiber when it becomes uncomfortable, because those tactics are familiar and require no new tools. That approach works some of the time, but it also fragments care:
Hydration slips
Fiber intake fluctuates
Dose escalation timings get missed
Side effects are hard to connect to specific behaviors.
Centralize Logs to See Correlations
Platforms like MeAgain help by centralizing medication schedules, hydration and nutrition logs, activity tracking, and symptom tracking, with reminders and visual progress, so users can see correlations quickly and adjust before problems escalate. Teams find that having one place to record what you ate, how much you drank, and when a symptom started lets patterns surface in days rather than weeks, restoring agency and reducing anxiety.
Simple Checks That Show Why This is Normal
A quick self-audit will often reveal the root causes in plain sight: smaller meals, less water in the bottle, fewer high-fiber choices, and a dose increase in the last month. Those four factors—slowed transit, delayed stomach emptying, reduced fiber intake, and lower hydration—add up in predictable ways. If you picture stool as a sponge, slowed transit lets the sponge dry out; less fiber means less sponge to begin with; and lower fluid intake means a drier result.

Stay Hydrated: Water Is Key
Aim for 2–3 litres of water each day. When stool slows and spends more time in the colon, extra fluid helps keep it softer so it passes without additional strain. Sip steadily through the day, for example, one small glass every hour rather than waiting until you feel thirsty. Soups, herbal teas, high-water fruits like cucumber or watermelon, and sugar-free electrolyte drinks all count toward your total. Drinking at least 2 liters of water daily can help alleviate constipation.
Add Gentle Fibre (But Don’t Overdo It)
Start small and build, because a sudden fiber jump often causes gas, bloating, and more discomfort. Try one gentle addition at a time:
Half a cup of oats at breakfast
One kiwifruit after a meal
A tablespoon of chia stirred into yogurt
A teaspoon of psyllium in a glass once daily
Increase portions slowly over several weeks rather than overnight, and pair any extra fiber with steady fluids so it moves instead of sitting. As a practical target, increasing fiber intake to 25–30 grams per day is recommended to help reduce constipation.
Keep Moving
Light activity nudges the bowel into action. Aim for 20 to 30 minutes a day, especially after meals; even a 10 to 15-minute brisk walk after dinner will help. If you have limited time, break movement into three 7–10 minute bursts; frequent, short sessions trigger gut motility more reliably than a single long workout. Simple core-friendly stretches, gentle twists, and standing leg swings are practical when walking is impractical.
Warm Drinks and Routine Help
A warm drink on waking often acts like a natural signal to the gut. Try a plain warm drink, such as water or herbal tea, within 30 minutes of getting up, and again after a main meal if you need a nudge. Keeping a consistent daily schedule for meals and bathroom time trains the body’s rhythm; rituals matter more than you think.
Watch Caffeine and Dehydration
Caffeine sometimes prompts a bowel movement, but too much can backfire by increasing fluid loss or causing jittery stomach cramps. If you enjoy coffee, balance each cup with a full glass of water and avoid relying on extra caffeine as your only strategy.
Use Short-Term Aids If Needed
When you haven’t gone for a few days and lifestyle steps aren’t enough, short-term aids can safely restore rhythm while you reinforce habits. Options include stool softeners such as Coloxyl or Coloxyl plus Senna, and osmotic laxatives such as:
Movicol
Lax-Sachets
Lactulose
Avoid daily use of stimulant laxatives unless a clinician prescribes them, and reach out to a healthcare professional if symptoms become severe or if you need repeated rescue doses.
Don’t Skip Meals Completely
Even with a reduced appetite, aim to eat small, balanced meals rather than long fasts. Include healthy fats like avocado, olive oil, or a handful of nuts; those fats help keep the stool pliable and support digestion. When meal size drops, prioritize a small portion of fibre plus a source of fat to maintain bulk and movement.
Increase Slowly and Listen to Your Body
If constipation surfaces after a dose increase, pause on further escalation and extend your current dose for an extra week or two so your gut can adjust. Track which habit change produces the first benefit, and only add one new tweak at a time. This slows the feedback loop and prevents compounding side effects, such as bloating or gas.
Most people manage this by patching tips together from different sources because it feels familiar and low effort, which makes sense at first. What that approach hides is fragmentation: hydration slips, fibre changes happen in bursts, rescue meds are used without a pattern, and the link between a dose change and symptoms stays fuzzy.
Platforms like MeAgain centralize medication timing, hydration, nutrition, activity, and symptom logging so users can identify which single habit shift provides the most significant relief, set reminders, and replace guesswork with precise, repeatable adjustments.
Change One Thing and Track
I know it’s frustrating when small wins on the scale are paired with uncomfortable days in the bathroom; you want to keep the medication, not stop it, and that conflict is real. The practical rule I share with clients is simple, concrete, and humane: change one thing, give it time, and track the result so you stop guessing and start improving. That next step is the one people underestimate, and it changes everything about how you actually stick with these habits.
